The cutter bit features a segmented, high-quality composite structure. The core tip is made of high-grade low-cobalt hard alloy material, with high hardness, wear resistance, and corrosion resistance, effectively resisting the high-intensity friction loss of rock and sand; the cutter body is made of 42CrMo high-strength alloy steel, and through precision quenching and tempering heat treatment, the hardness of the cutter body is controlled within the standard range, perfectly balancing hardness and toughness. It not only ensures cutting penetration, but also greatly improves impact resistance and fatigue resistance, fundamentally reducing problems such as broken cutter bits, tip breakage, and cracking in hard rock construction.
The product adopts an optimized streamlined tip structure design, with a scientifically reasonable force angle, enabling rapid entry into various soft and hard ground layers, and easily completing soil cutting, sand layer stripping, and rock breaking operations. Compared with ordinary cutter bits, it has lower drilling resistance and higher crushing efficiency, can adapt to the continuous high-intensity operation of high-power rotary drilling rigs, greatly increase drilling speed, effectively shorten pile foundation construction periods, and meet the high-efficiency construction needs of deep piling and large-diameter drilling and probing.
